To all whom it may concern.'

Beit known that I', ALBERT J. SLAUGH- TER, a citizen of the United'.States, residing at Washington, inthe county of Rappah'an nook and Stateof Virginia, have invented newv and useful4 Improvements in Bottle-Stpppers, of which the following is a specification.

This .invention relates to bott-le Stoppers, and has for an object toprovide an imy proved stopper of this character which can be applied tothe bottle without resorting to the use of permanent fastenings andconstructing the said stopper obviating the necessity of removing itfrom thebottle by means of extracting implements.

A still further Aobject of the invention is to employ a spring fasteningdevice engag- Fig. 4 is a section taken on the line 4 4 of` `Fia'. yl.

The bott-le neck 1' is provided with a flanged upper end 2 which isformed at diainetrically opposite sides to provide oppositely inclinedsurfaces.' Eachsurface is corrugated on its underside, as shown at 8 inFig. l of the drawing. The flange 2 is provided with diametrieallydisposed recesses 4 for a purpose to be hereinafter described.

Thejcap may be of metal or any other I "material which may be foundmost. desirable for the purpose intended. As illustrated, the cap isprovided with a depending peripheral flange 6 which extends downwardlyover the flanged 'end 2 of the neck. At the center the cap -5 isprovided Witha pivot stud 7' which extends through the body portion 84ofa clamp 9.. This clam is formed preferably from` a single lengti ofsheet metal or wire, and as illus- Ytrated, it is bent to form bowed sring-form- -ing portions'lO which extend `over the sides of the langedend 2 of the `bottle .and then under' the Hangs to form ownwardlylocking elements l1 which are of concaveconvex form in transversesection, as shown in Fig. 3 of the" drawing, for `locking engagementwiththe correspondingly corrugated surfaces 3 hereinbefore described.

rom the portions 3 lthe ends of the clamp extend downwardly against thesides of the neck, as shown at 12, and then outwardly from the neck, asshown at 13.- Eaeh ex tremity is then bent on itself, as shown, and theend 14 is extended upwardly to lie\di rectly against` the portion l2.From this construct-ion the end 15 of each of such .ex-

tremities lies directly under the locking element 1l to reinforce suchelementand to y' insure its positive engagement with the sunA face 3.

By forming theclamp to provide the outwardlyextending portions 13 itwill be seen that such portions may be grasped by the hand of ,theoperator to facilitate attachment of the cap 5 or removal. of the samefrom the bottle. ln removing the cap from the bottle the portions 13`are manipulated sothat they may be. sprung away from each othersufficiently to disengagethe elements 11 from the surfaces 3. then berotated so as to bow the portions l2 thereof into registration with thelsaid dia metrically. opposite recesses l1 Theehcap The clamp can' maythen be withdrawn from the bottle by moving the same upwardly from thevneck. The construction of the device described is extremely desirable inthat, owing to the provision of 'the surfaces 3 and the provision of thecooperating spring', clamp.

therefor, should theilatter' lose its resiliency after 4frequentadjustments on the bottlevitmay ybe engaged at new points on the sur-`faces v3. These surfaces eectively form` means to prevent rotation oftheclamplafter the same has been adjusted. lt is desirable to place apacking such as the washer shown at 16, between the cap and the neck totof bthe bottle. rlhis insures' a perfect air tight connection when theclamp is in applied position.
